WINDOW.

SPECIFICATION forming part of Letters Patent No. 703,600, dated July 1, 1902.

Application filed October 24,1901. Serial No, 79,852. (No model.)

To aZZ whom it may concern: 4

Be it known that LEDWAED KRAFT,'& citizen of the United States, residing'at Madera,

in the county of Olearfield and State of Penn'- sylvania, have invented a new'and useful \Vindow, of which the following is a specification.

The invention relates to improvements in windows.

The object of the present invention is to improve the construction of windows,"more especiallythe. construction of the sashes and the manner of mounting the same, and to provide a simple and efficient window capable of positively excluding'wind and moisture and of confining the heat within an apartment. 2

The invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended.

In the drawings, Figure l is a'vertical sectional view of a window constructed inaccordance with this invention. Fig. 2 is a horizontal sectional view of a portion of the window, illustrating the construction of a n1 etal-. lic wiudow strip. Fig. 3 is'a similar view illustrating the construction of a wooden window-strip. Fig. 4 is a detail vertical sectional view of aportion of the metallic window-strip.

Like numerals ofreference designatecorresponding parts in all thefigures of the drawlHgS.

l designates a window-frame-provided with upper and lower sashes arranged in pairs, the sashes or members of each'pair being guided on an expansible window-strip 2, which forms a guide for the sashes. The upper sashes? and at are arranged at the outside of the window-frame and are-connected by screws 5 or other suitable fastening devices, the inner sash or member of the upper set being interposed between a parting-strip G'andtheouter window-strip 2, and the outer member 3 being provided with extensions or flanges 7, which are arranged at the outer faces of the outer window-strips. The lower sashes 8 and 9 are connected by screws 10 or other suitable fastening devices, the inner sash of the lower set being interposed between the inner '6 and the inner window strips.

window-strips, as clearly shown in Fig. 3, and the outer sash of the lower set being extended beyond the side edges of the inner sash and arranged between the said-parting-strips By arranging the sashes in pairs, as shown, dead-air spaces are provided between the membersof each pair, which serve as non-conductors of heat and which operate to retain the heat within an apartment. The arrangement of the sashes also permits the sashes or members 3 and 8 to be readily detached in summer, if desired, without affecting the operation of the expansible window-strips hereinafter described.

Each of the window-strips 2 is composed of an outer fiXGdSBCtiOD or member 11 and an inner movable section or member 12, which is held in engagement with the adjacent sash by coiled springs 13, disposed horizontally and having their ends-fitted in suitable sockets 14:. The sections 11 and 12 are angular in cross-section, and the sockets are preferably tubular, as clearly shown in Fig. 2. The inner engaging section 12 is connected with the f xed section by bolts 15 and is supported by means of armsor-flanges" l7 and 18, extending horizontally from the'sections and overlapping each other, as clearlyshown in Fig. 4. The bolts,-which are disposed horizontally, limit the movement of the section 12 and are adapted to be adjusted to secure the desired friction-alengagement between the section 12 and the adjacentsash By this construction the sashes may be made to slide freely, and the yielding expansible weather or window strips obviate the necessity of employing weights or other'lnneans for balancing the sashes-a'nd prvent the sashes from rattling and effectually exclude air and moisture. The fixed section 11 is provided with an attachment-flange l9, which-is perforated for the reception of suitable fastening devices for securing the said section'l'l to the window-frame. a v

The expansible weather-strip. or windowstrip may be constructed of either wood or metal, and when constructed of wood the outer section 20 will be angular or L-shaped in cross-section, and the inner section 21 will sections 20 and 21 of the wooden windowstrip, and suitable bolts 23 are provided for connecting the sections to limit the movement of the section 21.

It will be seen that the window is simple and comparatively inexpensive in construe tion, that the yielding window-strips exclude air and moisture and at the same time prevent the sashes from rattling, and that sashweights and other sash-balances are dispensed with. It will also be apparent that the sashes 3 and 9 are adapted to be readily detached in summer, if desired, and that the removal of these sashes will not affect the operation of the expansible weather-strips.

The exterior of the window-frame and the sashes may be protected by a coating of waterproof paint or any other suitable material.

Changes in the form, proportion, size, and the minor details of construction within the scope of the appended claims may be resorted to without departing from the spirit or sacrificing any of the advantages of this invention.

What I claim is 1. In awindow, the combination of a frame having a parting strip, the upper and lower sashes arranged in pairs, the outer member of each pair being narrower than the inner member, and the outer member of the upper pair being provided with lateral extensions or flanges, and the Window-strips interposed between the side edges of the narrow sashes and the window-frame and composed of fixed sections secured to the window-frame, and movable sections yieldingly engaging the other members of the sashes, substantially as described.

2. In a Window, the combination of a frame, a sash, and a window-strip composed of fixed .and movable sections provided with sockets,

coiled springs disposed horizontally and fitted in the sockets and interposed between the sections, and an adjustable device for limiting the separation of the sections forvarying the pressure on the sash, substantially as described.

3. In a window, the combination of a frame, a sash, a window-strip composed of fixed and movable sections angular in cross-section provided with tubular sockets and having overlapping supporting-arms, springs fitted in the sockets, and means for limitingthe movement of the movable section, substantially as described.

4. In a window, the combination of a window-frame provided with parting-strips, expansible window-strips located at opposite sides of the parting-strips, and the upper and lower sashes arranged in pairs, the outer sash of the upper pair being provided with laterally-extending flanges arranged on the outer faces of the adjacent window-strips, substantially as described.

In testimony that I claim the foregoing as my own I have hereto alfixed my signature in the presence of two witnesses.

EDWARD KRAFT.
